microprocessor together with advanced GSM digital signal handling technology to creatively
research and produce GSM wireless mobile intelligent alarming system. It is a high integration of
digital speech, Chinese short messages, study-mode wireless coding, long-distance home appliances
controlling, short messages identification and other  technologies. When alarming, it will
automatically inform the theft condition and location through speech or short messages. It is stable,
reliable and safe. With humanization manipulation and telecom phone line removed, it can be
comprehensively applied  to shops, offices, villas, residence community, garage, storage and other
places at which wire phone network can not cover but protection needed. It is able to protect users’
property and personnel safety.  
■two groups of timing arming and disarming function, which leaves out frequent manual
arming and disarming
■ten defense districts, which can be set as normal, at-home, intelligent or closed types, etc.
■using phone (cellphone) or short message  to systematically set the host computer in
long-distance. Creatively compatible with China Mobile’s Fetion so as  to decrease short messages
cost made by users’ sending short messages to systematically set the host computer.
■four wire routes, six wireless defense district, defense district can be equipped with many
accessories.
■six groups of speech phone, three groups of short message receiving alarm phone, 10 seconds
ISD automatic leaving message record
■one group of normally open signal output,  which can be externally linked to appliances
linkage alarming output.
■many built-in speeches, letting alarm receivers know the accurate alerting location
■many built-in short message contents. Users can send short messages or use Fetion to check
the status of host computer. Short message content from alarming defense district can be
amended.  
■wireless intelligent study coding, compatible with 2, 262 normal encoding and a million
group encoding, convenient and flexible for adding or reducing accessories.  
■telephone (phone) long-distance telecontrol for arming, disarming, monitoring, talkbacking,
shouting, and controlling appliances, etc.
